100
How many spheres does Earth have?
Five
100
This is the breakdown of rock material by a physical or chemical process.
What is weathering?
100
This is the process by which sediment and other materials are moved from one place to another.
What is erosion?
100
These are created by mounds of sand that are deposited by wind.
Dunes or Sand dunes
100
What helps soil to form? (Name 1 thing.)
Breaking down of rocks, decomposition of living things, mixing of soil by living things.
200
What makes up the hydrosphere?
Liquid water on Earth.
200
Name one way that a rock can be physically weathered.
Answers will vary. (Examples - Pressure changes, animals, wind, water, gravity, plant roots, etc.)
200
This is the process by which eroded material is dropped.
What is deposition?
200
This is a large mass of moving ice that forms by the compacting of snow and natural forces.
What is glacier?
200
There are different factors that determine how long it will take soil to form. One of these factors is climate. In what climate does soil best form?
Soil forms best in warm, wet climate as opposed to cold, dry areas.
300
What makes up the cryosphere?
Frozen water on Earth.
300
Name one way a rock can be chemically weathered.
Answers will vary. (Examples - Oxidation, acid precipitation, acids in ground water, acids from living things, etc.)
300
What factors determine how much a stream erodes?
The elevation of the stream, the streams speed, the amount of water that a stream carries at one time.
300
What are the other three ways that erosion and deposition can happen other than water?
Wind, Ice, Gravity
300
Which horizon of soil (A, B, or C) has the most decayed organic material?
A Horizon
400
Rain provides water for living things. This is an example of what two spheres interacting?
Hydrosphere and biosphere.
400
This is the break down and wearing away of rocks by the action of another rock.
What is abrasion?
400
Name one landform that a stream can create.
Canyons, valleys, floodplains, deltas, alluvial plains.
400
There are two types of glaciers we learned about: alpine and continental. Describe what each type of glacier does to the land.
Alpine glaciers form mountainous areas where continental glaciers flatten and smooth the landscape.
400
What does soil pH measure?
If a soil is an acid or a base.
500
Give an example of the biosphere and geosphere interacting.
Answers will vary. (Example - decomposing organisms release nutrients into the soil, humans use the ground to build houses on top of)
500
What is a similarity between ice wedging and plant roots growing in a rock?
They both cause the crack in the rock to grow over time. They both can cause a rock to break as the crack becomes larger over time.
500
What are the two main factors that affect how quickly a coastline erodes?
Wave energy and rock hardness.
500
There are three things that can be caused by rapid mass movement. Name one.
Rockfall, landslide, or mudflow.
500
Which soil would be better developed: the soil on a hillside or the soil on a valley floor.
The soil on a valley floor because there are more organisms and water in the soil. The soil on the hillside would experience more erosion.
